Thanks for posting in our Support Center! I took a look at your account and am seeing that you work with a few different trade partners. Would you please let me know which retailer's ASNs you are looking at right now? I should be able to let you know the difference between those types with that information.

As for the Defaults, here is a link to a video that should help explain how to set those up. Let me know if you run into any issues or if you have any other questions. Thanks!
